The most common reasons a Suzuki Reno cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a Suzuki Reno cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When the throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

Troubleshooting Cruise Control Issues in a Suzuki Reno

When troubleshooting cruise control issues in your Suzuki Reno, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex ones. Start by checking for blown fuses, as this is a common and easily fixable issue that can disrupt the cruise control system. Next, inspect the brake pedal and throttle body, as any malfunction in these components can directly affect cruise control functionality. Utilizing a scanner can help you identify any error codes and verify the operation of the speed sensor, which is crucial for cruise control performance. If the cruise control remains unresponsive and the check engine light is illuminated, disconnecting the battery's negative terminal for a brief period may reset the system. Be aware of common reasons for cruise control failure, such as a faulty brake switch or engine-related issues, and remain vigilant while driving, as sudden failures can pose safety risks. By following this structured approach, you can effectively diagnose and address the cruise control issues in your Suzuki Reno, ensuring a safer and more reliable driving experience.

What Could Cause the Cruise Control to Malfunction in a Suzuki Reno?

When dealing with cruise control issues in a Suzuki Reno, it's crucial to understand the common problems that may be causing the malfunction. A blown fuse or a defective brake pedal switch can often disrupt the system's functionality, as these components are integral to the cruise control's operation. Additionally, problems with the throttle control system or the anti-lock braking system (ABS) can also lead to failures. For older models, a broken vacuum line may be the culprit, while newer vehicles might experience issues stemming from faulty switches, speed sensors, or even control module and engine control module (ECM) problems. It's also important to check for a faulty brake light or a malfunctioning brake switch, as these can prevent the cruise control from engaging. Lastly, if the check engine light is illuminated, it may indicate underlying engine-related issues that could affect the cruise control system. By systematically examining these potential problems, DIYers can effectively diagnose and address the cruise control malfunction in their Suzuki Reno.

Why is the Cruise Control Not Working in a Suzuki Reno?

When the cruise control in your Suzuki Reno is not functioning, it’s crucial to address the issue promptly, as neglecting it could lead to safety risks while driving. Common culprits include a blown fuse or a faulty brake pedal switch, which are relatively easy to check and replace. Additionally, problems with the throttle control system or the ABS can disrupt cruise control functionality, potentially leading to more significant issues if left unresolved. In older models, a broken vacuum line may be the source of the malfunction, and it’s essential to inspect this as well. If you notice intermittent operation or the CRUISE light failing to illuminate, it’s a strong indication that a blown fuse may be at fault. Ignoring these symptoms not only compromises your driving experience but could also lead to more extensive repairs down the line. Therefore, taking the time to troubleshoot these components can save you from potential hazards and costly fixes, ensuring your vehicle remains safe and reliable on the road.
